Application filed May 29, 19072 Serial No. 376,314;

To allrwhom it may concern:

Be it known that I, MARION W. Prrivnn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illi nois, haveinvented new and useful Improvements in Fixture supports', of which thefollowing is a specification.

This invention relates generally to im rovements in fixture supports,and particu arly to wall or ceiling, plates or brackets for lightingfixtures, such as for the lamps and controlling connections of vgasolene. lighting systems, the main object of the invention being toprovide a supportingplate or bracket.

which may be employed either for the purpose of supporting a lamp andconnecting the hydrocarbon feedpipe therewith or supporting andconnecting a controlling; valve with the hydrocarbon feed of supplypipe,whereby the supply'of the? hydrocarbon to all the lamps on a flour maybe controlled from a given point. I p i The invention consists of adevice of the character described embodying certain improved features ofconstruction, combination and arrangement of parts, as will behereinafter fully described and claimed, reference being had to theaccompanying drawing, forming a part ,of this specification, in which:-1 j; I

Figure 1 is a view in side elevation, the canopy appearing in section,of a wall plate or bracket constructed in accordance with my inventionshown in use as a lamp support and hydrocarbon feed pipe connection.Fig. 2 is a similar view showing the bracket employed as a support for acut-off valve controlling the feed of hydrocarbon from the supply pipeto a lamp or a series of lamps. Fig. 3 is a section through thecontrolling valve shown in Fig. 2. Fig. 4 is a central vertical sectionthrough the wall plate or bracket. Fig. 5 is a front elevation of thesame.

Referring to the drawing, the numeral 1 designates the improved wall orceiling plate or bracket, which comprises a body or attachingplate 2, ofany preferred form, and which is provided with a desired arrangement ofopenings 3 for the passage of screws or other fastening devices tosecure the same to a wall, ceiling or other suitable support. Integralwith the body or attachingplate and projecting forwardly therefrom is a"socket member 4 internally screw-threaded at its outer or forwardend,,as at 5, and having the rear portion of its bore or passagesmoothsurfaced to form. a combined hydrocarbon feed channel and: catchbasinor chamber 6. A nipple '7" is'integral with the upper rear portionof thesock'et 4 and extends vertically therefrom andis provided withexternal s'crew-threads'8 and abore or passage 9 communicating at itslower end with the said channel anol chamber 6.

In Fig. 1 I have shown the wall or bracket plate employed as asupportfor a lamp fixture 10 and connection for the hydrocarbon supplyor feed tube orpipe 11 leading from the hydrocarbon.- reservoir. Asillustrated, the lamp fixture 10 is provided with a feed ipi e i2located abeve its generatorpipe 13 aficl threade'djat its" rear; endasat 1a, for ins errron intq thesurewtnreaded end 5 of the 6 7 from thebracket.

' connecting joint.

t 4 b3 hich the lamp is supported The hydrocarbon feed pipe 11 isconnected with the nipple 7 in any suitable manner, as by providmg it atits connecting end with a tapered jam or metallic packing plug 15engaging the upper end of the nipple and partially projecting into thepassage 9 and retained in position by an internally threaded packing capor nut 16 engaging the screw threads 8, whereby the supply pipe isattached to the bracket plate in such a manner as to prevent anypossibility of leakage of the hydrocarbon at the A canopy 17, of theform and construction ordinarily employed, in connection with electricand gas lamp fixtures, may be secured upon the rear end of the pipe 12to shield and inclose the bracket and impart an ornamental finish at thesupporting point. This canopy is provided as usual with an opening forthe passage of the pipe 12 by which it is slidably fitted thereon so asto permit ready access to the bracket when occasion requires, and may besecured in position by set screw or other desired fastening 18.

In Fig. 2 wherein the bracket is illustrated as a feed pipe connectionand support for a cut-off valve controlling the supply of hydrocarbon toa lamp or series of lamps, the hydrecarbon supply pipe is connected withthe nipple 7 in the manner previously described. The controlling valvehere shown consists of a casing 19 externally threaded at its inlet 1end for insertion into the socket 5 and provided with a feed passage 20and a suitable I With a cut-off valve 22 controlling the passage 20,which latter is in con'miunication With an externally threaded dischargenipple 23 to which a feed pipe leading to an elevated burner or all of aseries of burners on a noor is coupled similar to the manner in p whichthe supply pipe 11 is coupled to the bracket nipple 7. 'l he bracketaccordingly may be employed as a support for a valve, such as described,located at any convenient point so as to be readily accessible for thepurpose of controlling the feed of the hydrocarbon fro n the supply pipeto a lamp located at any desired elevation or to a series of lamps or toall the lamps on the iioor of a building. lhe valve as thus arrangedWill serve as a main valve of the type required by various fireinsurance companies to enable the hydrocarbon to be completely cut oilfrom the source of supply to the burners in a room or all the burners011 a floor, as will be readily understood.

'ihe bracket may also be used as a connecting medium or combined supportand pipe connection in various relations and for central portion of saidplate and formed irith a bore of uniform diameter internallyscrewthreaded at its outer end and smooth-surfaced at its inner end, anda nipple extending upwardly at right angles from the boss in advance ofthe plate, said nipple being e?;- an) ternally screw-threaded andprovided with a bore of less diameter than the bore of the boss andintersecting the said smooth-surfaced inner end thereof.

In testimony whereof, I aliix my signature as in presence of twowitnesses.
